'HARRY IBWIN JEFFERS, OF FoRT sivtIyTH; ARKANsAs, AssIGNoRoF ONE-HALE To WILLIAM MoRRIs JFFERS. or

- i residinj.:r ati'lfort. Smitln'in the county of Sebastian and State of Arkansas, have inventeda new and Iniprrn'ed-lVall-lflng', of

which the following is a spccilication..

My invention primarily has for its object 4to provide an improred construction of -metallic plug or attaclnnent to bc used in brick,

stone or concrete bnildinzc's. to provide for conveniently and etfectirely attaching the necessarywoodwork-to the masonry without thenecessity ofjbuilding. the nsnal Wood blocks or fillers into the masonry, orrcutting holes in .the plastered Vwalls, andiztlr'iving pln gs therem. z

This invention eomprehcnds, generallya-n in'iproved construction of socket 1nember--; :ulapted to be built in the .wall dnring'con; struction, and for telescopically receix'ing--ai plug tl1 at i11terloeks with the main .socket member and arranged to receive the driven nail when the Wood 01' other members to be attached, is nailed thereover.

My invention, in its more complete nature, comprises a. main metallic `socket member formed with fianged portions to interlock With the masonri'y into which it is built` a supplemental socket plug` that telescopically eng'ages the main socket, interlocks therewith and is adapted for being adjustably held therein to form av bracket projection,

.and having' opposing clamping' faces for receiving the nails driven therebetween when used as a Wall plue'. i

i/Vith other objects in view that Will hereinafter appear, my invention consists in certain details of construction and novel arrangement of parts all of which will be hereinafter fully explained, specifically pointed out in the appended claims and illustrated in the accompanying drawings in which, I

Fignre l, is a perspective view that illustrates the main socket piece as being built np in the wall. Fig. 2, is a perspective view partly in section and illustrates the complete plug` on the wall and a Wooden mold piece nailed thereto. Fig. 3, is a perspect'ive view of the complete plug, withthe means for holding' the two parts positively interlocked. Fig. 4, is a perspective view of a slightly modified construction of the main socket piece. Fig. 5, is a plan view of the blank from which the main socket. piece is formed tjoRr sMI'rH. ARKANsAs. y

and, Fig. 6, is :a similar view of the blank from which the adjnst able socket.l piece is forined.

ln the .prz-ictieal construction, my invention (',o1np1'iscsa main and a snpple-menta-l member toteleseoi'a'lly engag'e the main member, both prefe1'al'1lyx being;` of sheet. metal and each vfbent lnp into shapefifroin a blank form'.: f: i

The main 111c111bc1.'.1-\, '1\'l.=1i".h 'forms' an anchor piece. .is in thefinatnre 'ofafiattened tube, theends of the two opposing Ilat faces a-m in the form shown in' l'lig's. 1, 2 and 311cinpf'bent in' op-posite directions'to'provi'de fianges u/;ai' that in practice are separated the width ofan ordinary building' Vbrick so as to be! readily tied intothe n'alh'while V building.

-, formsnch as'shown in Fit: t. it can bebent =to the..

ilesi1fed-sl`n1pe land, the part-s hcld o 'eth'er byjbendi'ngz theportions a' in oppositedirections at one'ed'e'e will bo clearly= und erstood from the d ra w ing.

In Fie's. 1, 2 and' 3 the main member A is shown as formed entirely'of a' smooth sheet metal plate with both ends of the tube like body open. When the plug is to be used in a concrete wall, the inner end of the said tubelike body A is closed as shown in Fig. 4, (see 14" so that the concrete cannot 1'1111 into the socket or tube portion of said member A, and in the said form shown in Fig. 4, the opposing or flat. facesl of the member are corrneated as indicated by 11," and the eorru- ;rations extend diagonally but in transverse direction for reasons presently explained.

So far as described, it Will be readily apparent that in buildingr the Wall the socket member A can be inserted atthe desired points in the Wall as the wall is being built, and .made to receive the other member l of the plug When trimming out With the Woodhave extensions?1'--' formedvertically but f outwa'rdlyinclined fflangescz-cz that serve to guide'the nailsdriven between the clamp- To positively hold the member Bwithin the member A and for faclitatingthe telescoping vof the two members,,the part B is of a shghtly vless width than the art A, so. that the looking -nail w can `be riven'. between the adjacent' edges of'thezmembersB. and A as best shown in Fig'. 3, it 'being un-- derstood, however, that theV looking: nail asv might as Wellfb'e d'rivenbetween'the'corrugations of two opposing flat faceszoffthe members AandB as shown in Figz.

While my invention is .more especiallydesivned as a wall plug, it maybe used-for other purposes since it` maybe workeddnt'o the front, walls of building to 'provide .extensible brackets for supporting orv fastening. signs, electric 'fixture etc., theretoor thereon. i. j i

The outer. `fiange of-ithe s'lida'ble member B may beornamental and the 'main-'socket or -sheet A made 'long enou `h..to.passwen- 'tirelythrongh .the 'brick wall:forsthefpurpose i of ventilation.

I-Iaving thus described my inventioinzwhat" 1 clailn a11l,desi1'eto secure by Letters Pat-- ent, isz- 1. A wall plug compr-isingin combination with a socket member having .means vforan'- chori'ng in a wall; a t-ubular member -for telescopically engaging-the socket and means for positively locking the tubular member to its set posltionsin the socket.

.outwardly to form .to afiattened tnbular shape,.the ends being bentf at rightfangles to .form Vertical flanges, combined with ga .upplemental portion formed of'asingle piece ofVL metal bent to.

form a fiattened tnbnlar body, for telescopically engaging themain member and' having its oute'r ends bent outwardly and lfia-red 'for directing the nail driven thereagainst..

3. The comb1nat1on..W1t-h the mam or socketmembe'r '-adapted'to' be 'built in va new` wall and having a'nchori'ng' flanges;v of: a

Vflattened vtubular` member of* slightly less width than the socket member and'adapted to vfit loosely therein7 the'v opposite walls of:

Vthe -tubular member being vcorrug'ated in the trans-verse diagonal dlrection, Vmeans for 'holding the-flat-tened Vmember in locked en-` gagement with the socket andhaving the outer'ends of its opposing fiat'faces Vflare'd Guides as set forth.

4; As a `-new article; a wall plug -compri-sing flattened tube' or socket'having fianges for'interlocki'ng with a Wall; 'andf another 'flattened tubularfmember for telescopically .engaging the socket member, said other member` having corrugated nai'l clamping surface, vand means for lockin the` sald other member at ltsset positlon -in the mam or socket members.
